It is true because the y and x will always be the same number and a vertical line has no slope thus equaling 0,0


Step-by-step explanation:
and
are two fractions that are greater than 1 but less than 2 with a denominator of 3;
The denominator is the lower number in a quotient
Numerator is the upper number in a quotient
To solve this problem, we need to think creatively:
A fraction is made up of a numerator and denominator.
The denominator in this case must be 3
The numerator can be any number;
since the solution of our fraction must be greater than 1, this implies that the numerator must higher than the denominator.
if the denominator is higher, we get a solution less than 1.
since the solution must be less than 2, the value lies between 1 and 2.
The solution to the problem is

Answer:
, where a is initial value.
Step-by-step explanation:
We have been given that Tobias sent a chain letter to his friends, asking them to forward the letter to more friends. The number of people who receive the email increases by a factor of 4 every 9.1 weeks. We are supposed to write the function to represent the given scenario.
Our function will be in form of
, where,
a = Initial value,
b = Factor of increase,
= Linear function to determine the time.
Since number of people receiving email increase every 9.1 weeks, that is 1 people is 9.1 weeks, so slope of the increase would be
.
Increase in number of people in t weeks would be
.
Upon substituting our given values in growth function, we will get:

Therefore, our required function would be
, where a is initial value.
